(very rare) ; D. Forsteni, (very rare) ; D. hexagonotus, (common) ; 

 Lycodon aulicus, (not common) ; Lye. jara, (rare) ; JBungarus cceru- 

 leus var. a, (not common), JVaja tripudians, (not common) and 

 Ojjhiophagus elaps, (not common), the former growing in the Terai 

 up to 6 feet, and the latter attaining occasionally 12 feet in length ; 

 Trimeresurus gramineus, carinatus and monticola (none, except the 

 last, common). 



Now of all these species, for most of which the ^locality t Dar- 

 jiling' (8000 or 9000 feet) has already been recorded, not a dozen 

 will be met with at that place itself, or even at elevations above 

 6000 feet. Within 1000 or 2000 feet of Darjiling I only observed 

 Track, fuscum, All. collaris, Comps. Hodgsoni, Trop. subminiatus, 

 junceus, platyceps and, I think, Himalayamis, Trim, monticola, 

 Bungarus and Naj'a, the two latter evidently following up food. 

 The lower we descend on the hill side from 6000 feet, the greater 

 becomes the variety of genera and species. 



The species of snakes which I received through Mr. Kurz from 

 the Pegu Yomah (between Prome and Tonghoo) are Typlilops 

 brammus, Simotes bicatenatus, Trop. quincunctiatus, macrops, jtmceus, 

 bellulus (n. sp.), Psammodynastes pulverulcntus, Tragops prasinws, 

 Dendroph. picta, Hypsirhina enliydris, Lye. aulicus and jara. 



Fam. Typhlopid^, 

 While examining a large number of Indian species of Tgphlops, 

 I found the proportion of the circumference to the length of the 

 body a useful character, and the number of longitudinal rows 

 of scales generally very constant. These two characters were 

 also regarded by Dr. Giinther as important in distinguishing 

 species, but Prof. W. Peters appears to have come to an almost 

 entirely contrary result, particularly regarding the latter. 



Typhlops Horsfieldit, (I. E.,* p. 173). • 



This species, as characterized by Gray and Giinther from typical 



sub-ocular being present. There are two black streaks at the side of the body, 

 one originating just above the orbit, and the other at about the middle of the 

 posterior edge of the same, they become confluent at the side of the neck, 

 joining two short streaks from the posterior edge of the occipitals, not forming, 

 however, a ring.

 British Iudia, published in 1864, by the Ray Society.
